WINDING-MACHINE.

Specification of Letters Patent. I Patented March 1Q, :1908.

Application filed July 19, 1906. Serial No. 326.889.

To all whom it may concern."

Be it known that I, SIMON IV. VVARDWELL, a citizen of the United States, residing at State of Rhode Island, have invented cering-Machines, of whic specification.

My invention is a winding machine for pro ducing cops or yarn packages of cylindrical the following is a in advancing layers of regular y disposed longitudinal extension instead of diametric ally. These cops are employed as filling form being disclosed in my pending applic'a t-ion, Serial No. 323137 filed June 23, 1906.

The following specification is a complete description of the invention, illustrated by the accompanying drawings, representing, respectively:

Figure 1, a'front elevation of the machine;

grammatic sectional view of the cop, showing the diposition of the layers; Fig. 4, a part sectional view on the line AA, Fig. 1, looking in the direction indicated by the arrow; Fig. 5, a detail view of the automatic traverseshifting' mechanism; Fig. 6, adetail view of the belt shifting arrangement; Figs. 7, 8, 9 and 10, views"v showing modifications of the guide advancing mechanism.

The machine herein described is designed to-produce a cop havin a cylindrical body, a substantially flat or s ightly tapered base Referring to Figs. 1 and 2, the tube or bobcontrolled by a'suitable agency, as the tight and loose pulleys 4 and 5. Adjacent and parallel to the winding s indle 3 is a reciproeating rod or bar 6 on w ich is mounted the guide holder 7, carrying the yarn depositing guide 8, and adapted to advance along the described. Y To produce a substantially flat-based cop i of thecharacter described, it is necessary to 5 de 'osit the yarn in superimposed layers'of Q posed of yarn and having-therequisite form is secured. Then the winding fcontinues H with a uniform but shifting traverse of the guide until the desired length of cop has been of the guide being varied by changing the point of shifting the member from one screw 70.

to the other.

In the invention of the present application I prefer to effect the traverse of tie guide through a stepped cam Q'having concentric faceslO, 11, 12, etc., formed with different lengths of throw, as shown in Figs; 1 7 Any suitable number of cam faces might be provided, but I prefer to show eight which provide for eightdiiferent lengths of layers of yarn in the core of the cop. It will be understoodfroni the drawings that the ste'pcf least diameter has the cam face of shortest- .throw, and. in each succeeding step the throw is increased uniformly until the maximum throw of the cam is reached, the latter deter mining the length of traverse of t-he'guidefbr building the main body of the copafter the coreis formed. It is ointed out that each cam face starts at a pomt not in line with the starting point of the tace beneath, but slightly offset therefrom for the purpose hereinafter described. The cam 9 is mounted on a shaft 13 driven from the spindle 3 through asuitable train of gearing shown in Figs. 1 and 2.

On the rod 6 is-fastened an arm 14 havinga roll or stud 15 extending toward the center of the cam 9 and adapted to bear on the faces 10, 11, 12, etc. The spring 16, fastened at 17 on the frame of the machine and to the en d 1 8 of the rod 6, maintains the stud 15 in contact with the cam faces. The rod 6 slides in bearings 1 9 and 20, being ca able ofrotati'on to rock the arm 14 and shitt thestud 15" fronr one step to another on the cam. The shifting of the arm 14 is controlled through an arm 21: pivoted on the rod 6, with its outer end adapted to bear on v the baseF-pof the cop as the latter is built'iupcnthe spindle Connected to the? arm'l21 is a frame 22, mounted on therod fi. adjacent the- =-b'earings l9 and 20, and having'a rail ortrack ortion 23; i The::arm..l.4 isrformed with brr as at taehed to it, a. lip portion 24. see Fig. 5, reaching down and bearing on the under side of the track'23 so that the arm 14, while. slidable on the track, is also adapted to be rocked by 'the rocking of the frame 22. A spring 88 fastened to theframe and. to the base of the machine tends to resist the upward movement of the frame.

Totheframe 22 is fastened a member 25 ,whichconnects said frame with the arm 21 through two pins 87, ST engaging either side of the arm, as shown in Figs. 2 and 5. The member 25 is formed at the bottom with a qua-drant'sectionhaving ratchet teeth 26, 27. etc., adapted to be engaged by a spring pressed plunger 28. The plunger is beveled at the top to provide a sharp edge for engaging the teeth of the ratchet and is mounted in the bore of a barrel 29 formed on the bracket 30 of the machine frame. Midway of the plunger is a ring or flange-31 against which the coiled spring 152 bears. tending to force the plunger upward against the memer 25, and a pin 33 extending into a groove or slot 34 in the barrel 29 prevents the plunger from turning. I I The teeth of the ratchet member 25 correspond in number with the steps on the cam 9. andare so formed that when the ratchet member 25 is moved sufficiently to release one tooth from the plunger 28, the latter then bearson the long face of the tooth, and. acting as a wedge, forces the member 25 away to shift the stud 15 from one step to another on the earn 9. This movement also removes the arm 21 from the yarn surface, and the frame 22 is locked in position until the yarn is built up on the spindle sufficiently to engage the arm 21 again. t i

The operation described in full is as followd: The winding is started with the stud 15 hearing on the face 10 of the cam 9 and the guide 8 in the position indibated by full lines in Fig. 1 and the arm H by dottedlines in Fig. 5. The arm 21 is then in the position indicated by dotted lines. Fig. 5. with the plunger 28 forced down in its bore and hearing on the tooth 26. The yarn is wound on the tube, 2-in the initial layer with a comparatively short traverse of the guide as shown in Fig. 3, and when built up to its predetermined diameter the surface contacts'with the arm 21. rocking the latter in the .direction indicated by the arrow. Fig". ThE' IIIOVEDIGIIt. of the arm 21 rocks the member 25. releasing .the tooth 26 from the plunger 28, and the latter then acts onthe member 25 to continue its movement sufficiently to shift the stud liclear of the step 10 on. the cam '9. The spring 16 now shifts .the rod (jto earrythe stud. 15 into engagementwith the ca m face 11, and the yarn guide is therebygiven an increased length of traverse. starting at. a positionslightly in achumce of the start of the first layer; The.

,ment with the cam face 11.

plunger is now engaged with the tooth 27 of the ratchet member 25 and retains the latterin proper position for the stud 1-5. guided by the track 22. to' remain in engageyarn guide at predetermined points is to deposit the yarn in successive layers and to cause the layers of yarn to overlap each other so that gradually the mass takes a conical form. as shown by dot and dash lines. Fig. 2. It will be understood that this tapered core might be built up with its base perfectly flat.

but'it has been found preferable to give a slight taper to the base to make it more stable. the outer layers being more firmly supported and less liable to derangement.

The arm 21 is The taper ofthe base results from the slight advance of the starting point of each layer of yarn caused the offset of the different steps on the cam. I i

The completion of the last layer of yarn on the core. wound with the stud 1-5 on the last step of the cam 9. brings the cop to the pre determined diameter at its base. and the stead of by diametrical increase. To effect this. the reciprocating guide feeds gradually along the rodfi. as now explained.

The reciprocating rod 6 is. formed with an extension 35 having partial'screw. threads 36. the axis 37 of "which is eccentric to the rod 6. see Fig. ,7. The guide holder 7 is mounted on the extension 35 of the rod 6. being forked. with each branch of the fork embracing said rod. and between the branches is a rotatable nut 38 engaging the partial screw threads 36 to feed the guide holder along the rod. The bore of the nut 38 is of sufficient diameter to provide clearance for the threaded portion of the rod 6 when the axes'of the nut and rod are in alineinent. but the bore is "threaded to engage the screw threads when ment with the threads '36 are piotided in the spring 39 wluch extends along the groove it] 111 the member-3.5 under the member 7, being turned up at its ends to retain it in position. as shown in T. The central portion of the spring is bowed out at -11 to engage the bore of thenut 38. By pressing-the nut .38

cop then' grows by longitudinal extension in-' in the direction indicated by the arrow. Fig.

I threads 36, and the guide holder may be i slid along the rod 6 to position it properly in relation to the spindle 3 at the beginning of the winding.

5 The automatic feed of the guide holder.

along the rod 6 is secured by action of the cop.- On the nut 38 is a wheel 42 of such diameter as to be engaged by the surface of thecop at its full diameter, as shown in Fig. 4. Each time that the guide 8'returns from the points 442, 45, etc., on the cop tube, to the points 46; 47, etc. on the ortion'of the winding-of largest diameter, Fig. 3, the wheel 42 is engaged by the cop surface and rotated slightly, causing the guide to advance slowly the arrow. a-,'Fig. 1.

It will-be understood that the guide is maintained in :close contact with the surface systematic laying of the coils.

Pivoted on the point of largest iameter, but so arranged as 1 guide holder 7 a from and approach the spindle as'it travels 11p. and down the taper;

The feeding of the guidealong the'rod 6 might be secured by other means as, for in-.

stance, those shown in Figs; 8, 9- and 10. In

acent the guide 8 is a friction wheel or roll 52 ada ted to bear on the surface of the co when t e guide reaches the to clearthe cop while the guide is traversing the tapered portion. The roll 52 is formed withan' eccentric hub or hearing 53 on which is mounted the pawl 54 having its opposite end engaging the teeth of the ratchet wheel 551; A suitable spring 55 bears on the end of 'ithe pawl to keepiit engaged with the ratchet wheel. As'esthe'roll 52 comes into engageme'nt witht'he periphery of the cop at the-end fof each completetraverse, after the core has -been bui' p; a partial rotation is imparted to the reciprocating the pawl 54 and,

The'position' of the belt is controlled by the belt shifter hinged. at 66 and movable manually into engagement with the lock 67 to shift the belt to the tight pulley 4; and when released by said lock, moved automatically by the spring 68 to shift the belt to the loose pulley 5. The lock 67 engages a detent 69 on the belt shifter, and is rotatable to release said detent under action of the stopping mechanism of the machine.

Referring to Figs. 1, 2 and 4, the arn 48 asses through the guide eyes 49 an 50 beihre entering the thread guide 8. 7 These guide eyes are mounted on wires fastened to a rocking frame 70 pivoted at 71 on the guide holder The outer/end of the frame 70 extends under a wire bail 72 which is pivotally mounted on the bar 6 between the bearings 73 and 7 4; A spring 75 fastened to the base of the machine and connected with the bail 72tends'to rock the'latter to bear on theend of the frame 70. The tension ofthe thread passing through the eyes 49and 5O maintains the frame 70 approximately the position shown in Fig. 4, and the springj75 serves to apply the "necessary pressure to: maintain the'guide in close contact with the surface of the cop. The bail 72 has an arm '76 extending downward and formed with an arcal piece 77 adapted to normally bear on a pin '78, see Figs. 1 and4. The pin'78 pro- JGCtS from the rotatable stud 7-9-which is formed with the lock 67 for the belt shifter 65, and,.with the .arm 76 inthe position shown in Fig.4, the lock is maintained in position to engage the detent 69 on the belt shifter 'to retain the latter in osition w render the machine operative-r The arcal fluence of slight changes in the tension on-the thread, but upon the complete relief ofthe tension, as when the thread breaks, the frame 70 will tilt-to such an extent as to allow the bail to rock sufiicientlv to remove the" arm .76from'its bearing on the pin 78."

To effect the stopping of the machine whenthe cop reaches its predetermined length, the following arrangement is provided: Near the outer end of the rod 6 the bail 72 is formed with an offset portion 81 so that when the guide reaches the end of the winding spindle the bail is allowed to rock, under action of its %)ring, to remove the arm 7 6 from the pin 78.' his causes the release of the belt shifter the movement ofthe handle 02, as described,
